Sofant designs tiny but powerful antenna

Sofant Technologies said it has designed a 4-square-millimeter antenna designed to boost wireless signal quality fourfold and save 90% on battery consumption. Based at Scotland's Edinburgh University, researchers said they built an antenna that latches onto a single strong signal instead of searching constantly to find the most powerful one. It could take up to three years to bring the product to market, CEO Sergio Tansini said.
